Problems solved by technology

Interface usability evaluation methods are roughly divided into three categories: subjective evaluation method, objective evaluation method and physiological measurement, but there are the following deficiencies: subjective evaluation methods mostly rely on simple qualitative description and subjective judgment, and the reliability is not enough; objective evaluation methods are difficult to Deal with the uncertainty a...

Embodiment Construction

[0039] Gray relational analysis is one of the common methods in fuzzy evaluation. By testing the similarity or difference between each plan and the ideal reference plan, it can realize the evaluation and screening of multiple plans. A decision is made on the selection of attributes.

[0040] Regarding gray relational analysis, matching gray relational analysis method, for the factors between two systems, the measure of the correlation size that changes with time or different objects is called the degree of correlation. In the process of system development, if the changing trends of the two factors are consistent, that is, the degree of synchronous change is high, it can be said that the degree of correlation between the two is high; otherwise, it is low. Therefore, the gray relational analysis method is based on the degree of similarity or dissimilarity in the development trend between factors, that is, the "gray relational degree", as a method to measure the degree of correla...

Abstract

The invention discloses a quantitative evaluation method for availability of a system interface. The method is that the rough number score in the test result is matched with an interval data of a subject under the corresponding evaluation index to express the fuzziness in system interface evaluation. Compared with the traditional method which is applied to different subjects to obtain different specific data which leads to the absolutization of the specific data, the method has the advantages that the scheme is evaluated according to the difference degree (quantification) between each scheme and the ideal scheme, and the problem of fuzziness in system interface evaluation can be removed by quantifying; the task-decomposition-based evaluation method for a complex interface is performed to decompose the interface which is difficultly directly evaluated into a plurality of sub-task interfaces, and therefore, the effective measurement of available indexes is improved, and undetermined problems can be decreased.

Description

technical field [0001] The invention relates to a system interface usability evaluation method. Background technique [0002] System interface usability has its normative definition in the International Organization for Standardization (ISO). Usability refers to the effectiveness of the interaction process, interaction efficiency and user satisfaction when users use products to complete specific tasks in a specific environment. In short, usability can be understood as the user interface should be easy to identify, understand and judge, to avoid misunderstanding or misjudgment by users. [0003] In some large-scale applications, such as fighter jets, ships, nuclear power plants, automobiles and other industries, the complex system interface (referred to as the complex interface) has been widely used. Due to the large amount of information and the intricate structure of the complex system control interface, the usability of the interface is direct. It affects the operator's i...
